error in code?

Guys,

will some one tell the error in the 3rd line in the code? I am new to c#.

if (UserDs.Tables["users"].Rows.Count == 1) {
// Response.Redirect firstGridPage.aspx;
formsAuthentication.RedirectFromLoginPage(UserName.Text, true);

}

or i want to redirect the user from the login page when the login is successful using the commented line. I am getting error there as well.

Please help me.

thanks

Sorry this didn't get answered sooner, probably should have posted it in the ASP.NET category. Anyway, here is the answer:

Code:

---

if (UserDs.Tables["users"].Rows.Count == 1)
{
      Response.Redirect("firstGridPage.aspx");
}
